screw rods or the like, it is necessary to loosen.

the bolts between the fish plates and the rails and the connections between the rails and the sleepers. ihese operations require a great .15 deal of time and such rail slewers are less adapted for portions of a line having a lively traffic.

It is an object of the present invention to overcome the above disadvantages. According to the invention the rail slewer comprises a U-shaped body and a wedge and the side portions of the U-shaped body form an angle which corresponds to the angle of the wedge,

so that the rail may be clamped between one side portion and the wedge. When the rail slewer is to be used the U-shaped body is applied sideways to the rail so that one side portion engages the lower side of the rail foot and the wedge is inserted between the other side portion of the U-shaped body and the rail head. Then the projecting end of the wedge is hammered or rammed in longitudinal direction. After a few strokes the rail will be securely clamped between the wedge and the U-shaped body so that further strokes will result in a displacement of the rail or line of rails.

Preferably a thrust bar is used for the operation of the rail slewer. This thrust bar may be mounted on rollers so that it is adapted to being easily moved forwards and backwards over a line of rails.

The advantages of such a thrust bar over a hammer will be readily understood from the following. A thrust bar will always strike tion together-within thrust bar;

exactly thesamc spotof-the head-of. the wedge and a correctiffinishingof the co -operating of thezthrust bar and the .wedge will allow these facesto contact overtheir entire surfaces. Accordingly the-.material of the Wedge! will nota be, perceptibly. deformed and the Pe-ntire quantity. ofrkinetic. energy which has been; accumulated-in the thrust bar'before thest-roke willbe available for the displacenlent of the rail nokinetic. energy being wasted {for the "deformation of the wedge. Furthermore, ,the direction of ,the stroke coincidesreziactly. Withtl1fi direction of the rail.

The length of the wedge 4: is about twice that of the U-shaped body 1, so that when using the rail slewer for rails of different heights contact between the wedge and the U-shaped body over the entire length of the latter is always ensured.

The upper and lower inner surfaces of the side portions of the U-shaped body and the contacting surfaces of the wedge have been planed, filed or milled. The width of the lower surface is determined by the greatest width of the foot of the rails to be handled; the upper surface need not be much wider than the wedge. the finished surfaces of the U-shaped body corresponds to the angle between the cooperating surfaces of the wedge.

To prevent rotation of the rail slewer about a vertical axis during operation the free end of the lower side portion of the U-shaped body may be provided with an inwardly directed flange 5 which determines the maximum width of the rail foot. However when rails are to be handled having feet which are smaller than the lower surface, a filling plate 6 may be laid over the lower surface. This plate 6 is'provided with a longitudinal groove having a width corresponding to that of the V rail foot. The flanges 7 secure the plate in correct position. The wedge is guided between the vertical portion of the Ushaped body and an inwardly directed flange 8 at the free end of the upper side portion.

In Fig. 1 the complete arrangement of the rail slewer and a thrust bar 9 mounted on two or more rollers 10 is illustrated. In practice this rail slewer has fully satisfied the requirements. It can be easily handled and can withstand the severest strain without being damaged, because it only comprises two almost unbreakable'parts.

What I claim is 1. A rail slewer comprising a body having a U-shaped cross section and a wedge, characterized in that the side portions of this body form an angle which is equal to the angle of the wedge, so that the rail may be clamped between one side portion and the wedge which is guided by the other side portion and is rammed or hammered in the operation of the device.

2. A rail slewer according to claim 1 in combination with a thrust bar which is mounted on rollers and is adapted for being rolledbackwards and forwards over a line of rails.

3. A rail slewer comprising a body having a U-shaped cross section and a wedge, characterized in that the side portions of this body form an angle which is equal to the angle of the wedge, so that the rail may be clamped between one side portion and the The acute angle between longitudinal groove having a width corre-- sponding with that of the foot of the rail.

In testimony whereof I aflix my signature.
